The North Star is Polaris, a moderately bright star at the end of the handle of the Little Dipper. It is not the brightest star, only around the 48th, but it sits less than a degree from the north celestial pole, so it stays almost perfectly still while every other star circles around it. Find it by following the two “pointer” stars at the end of the Big Dipper’s bowl.

How to find the North Star
The easiest way is with the Big Dipper (part of Ursa Major, also called the Plough in the UK and Saptarishi in India). Find the two stars that form the outer edge of the Dipper’s bowl, Merak and Dubhe. Draw a line from Merak through Dubhe and continue it about five times the distance between them. The first moderately bright star you reach is Polaris. You can also use the W-shaped constellation Cassiopeia, which sits on the opposite side of Polaris from the Big Dipper; the centre of the W points roughly towards it.
Do not expect a dazzling star. Polaris is about as bright as the stars of Orion’s Belt, and many people are surprised by how modest it looks. What makes it special is its position, not its brightness.
Why the North Star doesn’t move
As Earth spins, the whole sky appears to turn around two points directly above the North and South Poles, the celestial poles. Polaris happens to sit very close to the northern one, less than a degree away. So while other stars rise, cross the sky and set, Polaris traces only a tiny circle and seems to stay in the same place all night and all year. Long-exposure photographs of the northern sky show every other star drawing a circular trail around it.
That stillness makes Polaris a natural compass. Facing Polaris means facing true north (within about a degree), and its height above the horizon is almost exactly equal to your latitude. From New York (about 41°N) Polaris is about 41° up; from London about 51°; from New Delhi about 29°; from Mumbai only about 19°; and from the equator it sits right on the horizon. Navigators used this for centuries to find their latitude at sea.
Can you see the North Star from the Southern Hemisphere?
No. Because it lies over the North Pole, Polaris is below the horizon for anyone south of the equator (in practice, it is very hard to see south of a few degrees north because of haze near the horizon). The Southern Hemisphere has no bright pole star; its south celestial pole lies in a faint patch of the sky in the constellation Octans. Southern observers find south using the Southern Cross and the two Pointers, Alpha and Beta Centauri.
What kind of star is Polaris?
Polaris is a yellow-white supergiant, roughly five times the mass of the Sun, about 46 times its diameter and well over a thousand times as luminous. It is also a Cepheid variable: it swells and shrinks slightly every 3.97 days, changing its brightness by a few hundredths of a magnitude, too little to notice by eye. Cepheids are important because their pulsation period reveals their true brightness, which lets astronomers measure distances across the universe. Polaris is the nearest Cepheid to us. It is also a triple system: a small telescope shows a faint companion, Polaris B, and a third star, Polaris Ab, orbits much closer to the main star. In 2024 astronomers using the CHARA array of telescopes published the first detailed images of Polaris’s surface, revealing large bright and dark spots.
Will Polaris always be the North Star?
No. Earth’s axis slowly wobbles like a spinning top, a motion called precession, completing one circle about every 26,000 years. Polaris will come closest to the pole around the year 2100 and then slowly drift away. About 4,700 years ago, when the Egyptian pyramids were built, the pole star was Thuban in Draco. In around 12,000 years, the bright star Vega will be close enough to the pole to serve as a dazzling North Star.
Frequently asked questions about Polaris
Is the North Star the brightest star in the sky?
No. Polaris is only around the 48th brightest star. The brightest is Sirius. Polaris is famous because it marks north, not because of its brightness.
How do I find the North Star?
Find the Big Dipper, then follow the two stars at the end of its bowl (Merak and Dubhe) about five times their separation. The moderately bright star you reach is Polaris.
Does the North Star move?
Almost not. It traces a tiny circle less than a degree across around the north celestial pole, so it appears fixed while the other stars turn around it.
How far away is the North Star?
Polaris is about 430 to 450 light-years away. Different measurements still disagree slightly.
Can you see the North Star from India or Australia?
From India, yes: it is low in the north, at a height equal to your latitude (about 19° in Mumbai, 28° in Delhi). From Australia and the rest of the Southern Hemisphere it is below the horizon.
